Flood-dragon tribe's arrival caused many people's faces to fall serious.
Their combat strength was the absolute strongest among their level.
Of course, their strength was only relative, as the combat strength of Human peerless geniuses exceeded the bounds of cultivation.
Su Mo knew he had to be wary in Fighting Spirits' Plane.
Soon after the Flood-dragon tribe arrived, a few other Demon tribes arrived as well.
There were five dominating Demon tribes in Firmament World. Besides the flood dragons of the East Sea, there were the Burning Clouds Island of the South Sea, Raging Sharks of the West Sea, Demons Mountain, and Sky Lake Palace.
Many experts of these four tribes arrived, appearing no weaker than the nine great Human sects.
The Raging Sharks of the West Sea were even rumored to be on par with the flood dragons, making them very powerful.
Everyone was waiting.
